Not able to get the final rendered output(when f12 is clicked)
To configure a render please be sure of the following :

you have an active camera in your scene and that the camera is pointing to your object
go to the render properties panel here and check what rendering engine you're using (Eeve or Cycles)

go in the output properties panel here, and check that you have a good resolution

And make sure you have a light in the scene ! (or an HDRI setted) in order to be able to see something.
Check that you don't have scrolled out too much in the rendering view window

If you still have the issue, try opening a new scene in Blender and render the default cube to check
